Patent CA-2332720-A1 (CA)
Title: Resonant capacitive coupler
Inventor: SCHWARTZ RICHARD F
IPC: H01P1/04
Filed: 2001-01-29
Abstract: A resonant capacitive coupler (124) couples signals across a gap (126) between signal transmission lines (112, 118) of two printed wiring boards (100, 102). The coupler has a conductive contact member (202 or 302) that is either positioned in close proximity to one of the transmission lines (112) or is connected to the one transmission line via a dielectric (204 or 304), and forms a capacitor therewith. The coupler further has a conductive interconnect member (200 or 300) that is connected to the contact member, and also to the other transmission line (108) either directly (FIG. 3) or via a second conductive contact member (202) (FIG. 2). The conductive interconnect member is dimensioned to have an inductive impedance at the frequency of the signals that equals, and hence cancels out, the capacitive impedance of the one or two capacitors formed by the one or two contact members. The coupler therefore resonates at the signal frequency, and relative to conventional capacitive coupling achieves a low-loss interconnection over large gaps while requiring only small capacitance to do so.

Title: Seal for sectional door
Inventor: MILLER JASON D
IPC: E06B7/22
Filed: 2001-04-17
Abstract: A seal assembly for an overhead-storing door seals the horizontal joints between adjacent panels of the door. The panels are pivotally interconnected at the joints to allow the door to open and close by traveling along a set of lateral tracks that curve between horizontal and vertical. The door closes in the vertical position, and stores horizontally overhead. The seal assembly can also be used for sealing the leading edge of the door panel that closes against the floor. The seal assembly includes a seal holder with a T-shaped anchor that engages a complimental T-shaped seal-receiving opening in a foam core of at least one of the door panels. The seal holder includes shaped grooves for attaching a flexible U-shaped seal member and, if desired, for inserting a reinforcing bar that increases the rigidity of the seal holder. In attaching the seal member to the seal holder, the T-shaped anchor slides in a first direction into the mating seal-receiving opening in the foam core. The sliding fit in a first direction provides a positive connection in another direction perpendicular to the first. This ensures that the seal holder is held firmly in place when in use, yet is readily installed or replaced.

IPC: G06F21/31
Filed: 1999-09-24
Abstract: A method and system of remote verification of an end user of web page with controlled access. Users are issued a user name and password which can be used to access any site which subscribes to the described verification system. A  user connects to a web site which contains desired information. When the user attempts to enter an area (or page) of the site with controlled access the pre-issued user name and password are requested. Once this information is entered, the subscribing website sends a secure (encrypted) query to a remote password database server. The supplied information is checked against a verification database. A yes or no secure verification is sent back to the subscriber site.  This verification can include anonymized demographic information such as specialty, location, and type of practice. The subscriber site then acts upon the verification received. The information entred by the user, while sent by the subscribing site is not accessible by the subscribing site. Thus, the subscribing site cannot create its own database of pre-verified users.  Preferably users are not required to be preregistered, and can gain access by entering identifiers which are checked against official Medical Association records. Preferably, whenever a user accesses a Web site and provides basic demographic data, the image of the sales representative most likely to deal with that user (based on location, zip code, or area of interest, etc.) will appear on the user's screen. The web site gets enough of the data entered by the user to select the proper sales representative, but not enough to target the user with solicitations.

The transmitter-generic--chip-code generator (101) generates a generic-chip-code signal and the transmitter-message-chip-code generator (102) generates a message-chip-code signal. The EXCLUSIVE-OR gate (103) spread-spectrum process message data with the message-chip-code signal to generate a spread-spectrum signal. The transmitter (107) transmits the combined generic-chip-code signal and spread-spectrum signal, on a carrier signal (108) over the communications channel as a spread-spectrum-communications signal. The receiver-generic-chip-code generator (121) generates a replica of the generic-chip-code signal. The generic mixer (123) recovers the carrier signal from the spread--spectrum-communications signal. The receiver-message--chip-code generator (122) generates a replica of the message-chip-code signal. The receiver-message mixer (124) despreads the spread-spectrum-communications signal as a modulated-data signal. The tracking and acquisition circuit (121) uses the recovered carrier signal for synchronizing the replicas of the generic-chip-code signal to the recovered carrier signal. The synchronous detector (139) synchronously demodulates the modulated--data signal as received data.

Title: High efficiency electro-optic molulator with equalized frequency response
Inventor: HORTON TIMOTHY
IPC: G02F1/225
Filed: 2001-09-21
Abstract: A high-efficiency electro-optic modulator with an equalized frequency response is described. The modulator includes an optical waveguide formed in an electro-optic material that propagates an optical signal along a first direction of propagation. An electrical waveguide is formed on the electro-optic material and positioned generally co-linear relative to the optical waveguide and in electromagnetic communication with the optical waveguide. The geometry of the electrical waveguide is selected to achieve a modulation efficiency at a frequency in a bandwidth of a digital spectrum. A compensation network is electrically coupled to the electrical waveguide at a junction. The compensation network reduces an electro-optic response of the electro-optic modulator below the mean frequency bandwidth of the digital spectrum, thereby causing an increase of the electro-optic response above the mean frequency of the digital spectrum.
